First defect I noticed with the Phantom 4 are those plastic tabs on the top of each motor for the prop connection - they appear to be plastic. Props on and off in all types of weather could cause breakage if not careful.

I'm chatting with the DJI website and even they don't know the size of the craft. All they know is it's bigger. Has anyone else found the size, in comparison to P3? I'm mostly concerned about being able to put it in a backpack and carry-on airlines. If it's bigger, I have a doubt that's possible. However I've found this side by side video capture that makes them look identical in overall size.

This video shows testing of the tracking feature, and states the GPS mode in P4 is slower than P3. Only the sport mode does 40+MPH.

Here you go. They look extremely similar in size in width (side to side). However, in height, if you look at the base of the motors they are pretty close, but since the Phantom 4 has the motors on top of the plastic, they stick up higher. Finally, considering most existing backpacks place a piece of molded foam on the top portion, I would say all one has to do is remove some of that form in order to have the Phantom 4 fit an existing backpack.
